Indicates the type of a Command object.
Settings and Return Values
Sets or returns one or more CommandTypeEnum values. You can also use the adExecuteNoRecords constant from the ExecuteOptionEnum to improve performance by minimizing internal processing. This constant never stands alone; it is always combined with adCmdText or adCmdStoredProc (for example, adCmdText+adExecuteNoRecords). An error results if adExecuteNoRecords is used with the Open method, or a Command object used by that method.
Remarks
Use the CommandType property to optimize evaluation of the CommandText property.
If the CommandType property value equals adCmdUnknown (the default value), you may experience diminished performance because ADO must make calls to the provider to determine if the CommandText property is an SQL statement, a stored procedure, or a table name. If you know what type of command you're using, setting the CommandType property instructs ADO to go directly to the relevant code. If the CommandType property does not match the type of command in the CommandText property, an error occurs when you call the Execute method.
